there are just two human in this whole drama,
others are worst then animals

FL is evil,
pure evil who try everything to torture already depressed ML
SML is a attempted murderer who is free to murder his brother Again because Korean Laws SUCK criminals Cock every day

in Korea drug use is sentenced 1 year
rape is sentenced 7 days
attempted murder is FREE of any punishment
and if you succeed in murder you will be awarded Medal of honor by President
more severe your crime more lighter punishment you get

at end of it all YOO te O was framed for everything and all other were innocent
how does just one person conducted whole experiment
what FL did after her subjects death is to put same on ML
and request was made by his brother who was rumored to be attempted murder of his own brother

SML and FL try to kill ML at least two time and failed
and they did not face any punishment because its KOREA CRIME Heaven
